Buttoned Camas

#73a5ea
Notes

Buttoned Camas (#73A5EA) is a true azure with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (215°, 74%, 68%) places it in the balanced band at a mid lightness. It works across type, buttons, and borders, saturated enough to feel deliberate but balanced enough to not fight the rest of the palette. For a confident two-color system, pair it with its complementary amber. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Buttoned
adjective

Old French bouton, button — past-participle of button. As a color modifier, buttoned implies a clear-and-fastened-and-formal quality, the crisp color of Edwardian-period formal-attire fully-fastened-and-formally-dressed gentleman's-attire. Sits at the crisp-and-finished end of the grid, parallel to trim and pressed in usage.

Camas
noun

The genus Camassiacamas lily, North American native bulbs whose deep-blue flower spikes were a staple food source for Pacific Northwest Indigenous peoples (the bulbs are cooked in pit ovens). The color refers to a C. quamash meadow at peak bloom: a saturated, slightly cool deep blue with the satin finish of six-petaled lily-form flower.
